Sveum: Navarro not Garza's personal catcher

The Cubs are trying to trade Matt Garza before the July 31 deadline, and the better Garza looks, the better chance they can get more young talent in return.

Garza has dominated his last two starts with Dioner Navarro behind the plate, but manager Dale Sveum wouldn’t call Navarro Garza’s personal catcher over Welington Castillo.

“Well, I’m not going to sit here and say he’s going to be his personal catcher,” he said. “It worked out that way (Friday). I really wanted ‘Welly’ to catch all four games in St. Louis to kind of be involved with the best catcher in baseball (Yadier Molina), to see the similarities and to compete against the best guy in baseball.

“Obviously we want Welly to get to that level or somewhat near it anyway. I really wanted to him to play those four games against the Cardinals. Obviously the schedule worked out to where Navarro could play anyway.”

Garza is scheduled in Milwaukee next Thursday. Will Sveum consider Navarro for that start?

“I’m not going to lie to you and say it’s not a thought,” he said. “If it works out, I’m not going to just put him in there for that reason.”

So he doesn’t believe in the concept of a personal catcher?

“Obviously I know it’s worked in the past, but it’s not something I like doing when Welington is our future and our mainstay guy,” he said.

DeJesus watch:David DeJesus is not close to starting baseball activities, and will miss about a month with his shoulder sprain. He said he didn’t know if he would be back before the All-Star break on July 15.

“We’re not putting a timetable on anything,” he said. “We just want to see how it goes, but I want to get back out there. It’s tough just sitting here watching the games, but I understand it’s a process. I don’t want to go out there and get back on the DL again. I want it to be healthy enough to go hard and grind the rest of the season out with the guys.”

Extra innings: The Cubs dealt Triple-A Iowa pitcher Hisanori Takahashi to Colorado Friday for either cash considerations or a player to be named later… Steve Clevenger’s rehab stint at Iowa ended, but he felt tightness in his left side Friday and will begin more rehab in a few days… The Cubs signed sixth-round pick Scott Frazier, a right-hander out of Pepperdine… Brett Jackson was placed on Iowa’s DL with a right calf strain.
